3 Claims. (Cl. 229-31) This application is a division of pending application Serial No. 375,306 filed January 21, 1941 for Cartons, now Patent No. 2,447,243.

Our invention relates to cartons, more particularly to cartons of the foldable or collapsible type usually supplied in the fiat by the manufacturer and erected or set up by the packer. Specifically it is related to that type of carton having double walls with air space and to cartons having double walls without air space.

One of the objects of our invention is to provide a carton of the above-mentioned style having neater ends and more finished appearance generally.

Another object is to provide a carton made up from a blank on which printing and/or other finish desired need be impressed on one of its faces only no matter where it is to appear on the set up carton.

Another object of our invention is to provide a carton which may be made up from a blank having one finished side only and yet designed that only this finished surface will appear throughout the carton resulting in a product of good appearance made economically by the use of the thus permitted cheaper material.

A further object is to provide a more sturdy carton generally, having stronger ends, the inner section of which need not be provided with lateral locking means as is the case in cartons of this type made according to common practice and a carton having additional infolded corners.

A still further object by no means of lesser importance is to provide a carton which may be set up much more quickly than is possible with other cartons of this nature.

Other objects as well as many advantages of our invention will become apparent in the following description thereof supplemented by drawings illustrating a true embodiment thereof.

. walls exhibit the one surface of the blank so that a blank may be printed on one face and in one operation for matter to appear on any of the above-mentioned surfaces when erected.

Another departure from previous forms resides in the location in the blank of the inner and outer wall sections with respect to the bottom. In the former practice the outer side of the double wall I followed the bottom portion after being definedby a crease and the bottom extended underneath the wall. In the present case the inner wall section is adjacent the bottom section integrally, and is followed by the top spacing portion and outer wall-section which in turn is followed by the lower wall-spacing section which is continued to form the doubled bottom. One important result of this construction is that the side walls and the end walls are for all intents and purposes identical and that all four inside surfaces form a continuous wall integrally adjacent the bottom.

In the drawings:

Fig. 1 is a perspective view of a carton according to this invention fully erected;

Fig. 2 is a plan view of an extended blank from which the carton of Fig. 1 is set up.

Fig. 3 is a transverse sectional view of the blank of Fig. 2 in its folded or knocked down position.

Fig. 4 is a cross-sectional view of the erected carton of Fig. 1 with its cover closed.

Fig. 5 is a fragmentary sectional View of certain parts of Fig. 4, but showing the cover as retained in an opened position.

Fig. 6 is an underside view of one end of the erected carton.

Fig. 7 is an extended plan view of one half of a modified blank.

Fig. 8 is a fragmentary bottom plan view of a portion of a carton erected from the blank of Fig. 7.

Fig. 9 is a vertical sectional view through the carton end of Fig. 8, as seen from line 9-9 on said Fig. 8.

Similar reference numerals denote identical parts throughout the drawings, and although difference is alluded to ends and sides it is to be noted that these statements are for reference purposes only since in practice all sides may be made equal in length or again the longer walls may correspond, so far as their construction or that part of the blank used'are concerned to what are termed ends and vice versa throughout this specification and claims. v

Referring to'the drawings, [5 denotes'the inner bottom or in any event the bottom, [6 the inner section of the side walls, l1 the outer sectionof the side walls, while I8 and [9 denote the inner sections and outer sections respectively of the end walls. The upper sections'and lower sections of the side walls are denoted by numerals 20 and 2| respectively. The end wall upper and lower sections are denoted by numerals 22 and 23 respectively, the latter also serving in one form of the invention as a tab to removably fasten the outer end walls to the bottom. I I I It is to be noted that all sections of the carton side of the inner bottom preferably by means-bf adhesive. In the blank all inner wall sections are joined together by squares 23' which havean angular crease permitting each square portion to be folded in two when the carton is erected then 4 By providing the blank with a slit 34 substantially at the transverse center of the blank of Fig. 2 and on the crease of fold line between the outer cover panel 26 and outer section 11 of the back wall a relatively stiff piece of material 35, such as "cardboard;- mayl'be arranged "for maintaining the cover in an open -positionfas illustrate'd 'in Fig. 5. In order to position the lid or cover of the carton as illustrated in Fig. 5, the cardboard strip 35 is inserted through the slit 34 and positioned upwardly between the cover panels 26 and 33 and is thenworked downwardly into the air space of the Ib'ack 'wall' between its inner and outer wall sections whereit' is retained as is readily evident folded in that space between the end wall 'sectioris, 15 froman .inspectionzef Fig. 5.

thereby holding the walls' together. For better corner finish and enhanced rigidity the outer side wall sections are provided with tabs'29 folded inwardly of the bottom end walls. The blank, in addition and intermediate its ends, includes panels 26 and 33 which together form'a'cover for the carton.

In the making of the carton, 'po'rtion 2411f the blank is fastenedto portion l5 while the same What =is claimed is:
